STOVEPlPE-THIIVIBLE.

SPECIFICATION forming part of Letters Patent No. 79%,301, dated July 11, 1905.

Application filed October 29,1903. Serial No. 179,068.

T 0 all whom it 'lnmy concern.-

Be it known that I, RICHARD TOMKINS HoL- TON, a citizen of the United States, residing at olfe City, in the county of Hunt and State of Texas, have invented a new and useful Stovepipe-Thimble,of which the following is a speciiication.

This invention relates to improvements in stovepipe-thimbles such as are used in connection with stovepipes where the latter are to be carried through walls or ceilings or other partitions for the purpose of protecting said partitions against ignition when the stovepipe passing therethrough becomes overheated, the object of the invention being to provide an article of this class which shall be simple, durable, and efficient in operation.

With these ends in view the invention consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view showing a stovepipe-thimble constructed in accordance with the principles of the invention. Fig. 2 is a vertical sectional view showing the device applied to a partition-wall and extended into an adjacent chimney. Fig. 3 is a sectional view showing the device applied to a ceiling and extended into a superimposed chimney-flue.

Corresponding parts in the several figures are indicated by like characters of reference.

In carrying out this invention a sheet-metal cylinder 10, which may be an ordinary stovepipe, is provided at one end, which may be called the outer end, with an annular bead or flange 10.

14 is a sheet-metal cylinder of larger'diameter, having at its outer end an annular flange 14.

15 is an annular head having a central opening of a diameter equal to the exterior diamin engagement with the flange 10, the outer circumference of said head being turned or beaded upon the flange 14 of the pipe 14, which is thereby held suitably spacedv from the inner pipe. An additional annular head 16 is provided, said head being provided at its inner circumference with a flange 16", exteriorly engaging the pipe 10, and at its outer circumference with a flange l6, exteriorly engaging the pipe let. The latter may be of any desired length; but it is always shorter than the pipe 10, with which it may be connected by means of rivets 16, passing through the flange 16 The outer pipe 1 1 is provided with ventilating-openings 16, and the head 15 is provided with similar openings 15.

Secured exteriorly to the pipe 14, near the outer or front end of the latter, are strips of sheet metal constituting brackets 17, through athe extremities of which nails may be driven for the purpose of securing the device in position for operation.

The inner end of the inner pipe 10 is provided with incisions 18, forming a plurality of tongues which may be bent or flattened upon the interior of the chimney or fine with which the device is connected.

The operation of this device and its advantages will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed.

In Fig. 2 of the drawings, 11 designates a wall, and 12 a chimney disposed at a short distance from said wall. The chimney has the flue-opening 20, and an opening of suitable size is formed in the wall registering with said flue-hole, as shown at 21. Previous to assembling the parts of the thimble the outer pipe 14 is cut to a suitable length, which should be equal to the distance between the inner side of the wall and the outer side of the chimney. The head 16 is then placed in position and secured, after which the thimble is placed in position, as shown in Fig. 2, and secured, if necessary, by nails passing through the brackets 17. If the flue-opening of the chimney is located above a ceiling, as in Fig. 3, the thimble is made to extend through an opening in the ceiling, as will be readily seen by reference to Fig. 3. The openings 15 and 16 provide free ventilation,

whereby overheating is prevented and danger of igniting the walls or ceiling through which the Stovepipe passes is avoided.

Having thus described the invention, what is claimed is- A stovepipe-thimble comprising the following instrumentalities, namely, an inner pipe or flue having a flange extending annularly at its front end; an outer pipe or drum having an outward-projecting annular flange at its front end, and an annular head beaded upon said flange and provided with an aperture of a diameter equal to the exterior diameter of the inner pipe against the flange of which it is designed to abut; and a rear annulus constituting a spacing member between the pipe and the drum, said annulus being provided at its outer edge with a forwardmy own I have hereto aflixed my signature in 3 the presence of two witnesses.

RICHARD TOMKINS HOLTON.
